AUBURN, Alabama -- Linebacker Kris Frost, a five-star signee last February who figured to be in the playing rotation at Auburn this season, says he will have surgery Tuesday after injuring his shoulder during a workout this summer.

He reported the news via his Twitter and Facebook accounts. He could be ticketed for a redshirt season.

"Surgery Tuesday wish me luck guys," Frost tweeted.

Rivals rated Frost a five-star prospect and the No. 2 outside linebacker in the nation for the 2011 signing class.

He had a total of 178 tackles in his final two high school seasons at Butler High School in Matthews, N.C. He said he wanted to try playing receiver at Auburn.
